AUTQMATIC ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent Ida 390.383, dated October 2, 1888.

Application filed February 15, 1888. Serial No. 264,090.

To aZZ whom it may concern: v

Be it known that I, EDWARD C. MAGN Us, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Motor for Advertising or other Devices, of which the following is a full, clear, and exact description.

My invention consists in mechanism comprising springs and weights for utilizing the jolting, trembling, orswinging motion of public vehicles-such as cars, stages, steamboats, &c.or of supports or frames of any description to which a sign may be attached, for giving motion to parts or to the entire surface of signs or advertising cards or devices.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, showing one of the many ways of applying my motor, is a broken front elevation of a sign having my invention applied thereto. Fig. 2 is a sectional elevation of the same; and Figs. 3, 4', and 5 show modifications of the motor.

A represents a disk journalcd upon the axis 13, which may be supported in any suitable frame or casing, O. The edge of the disk A may be notched, as shown at a, Figs. 1 and 3, or it may be plain, as shown in Figs. 4 and 5.

D represents weights forturning the disk A. These weights are each supported wholly or in part by a coil or other spring, the former kind hei n g here represented and designated by letter 1*]. In the form of motor shown in Figs. 1 and2 each weight is supported entirely by the spring E, attached at its upper end to the frame or casing G, and each weight is provided with a rack-bar, G, the teeth of which engage with the teeth of the disk A. so that the upand-down motion of the weights (either or both) incident to the motion of the sign and permitted by the spring will communicate rotary motion to the disk A, turning it 011 the shaft or axis B. In Figs. 1 and 2 the letters H of the sign are held in front of the disk A, and the surface of said disk is in different colors, or it may be ornamented in any suitable manner, so that its motion caused by the weights 1) will attract public attention.

(No model.)

In Figs. 3, 4t, and 5 the sign letters or devices may be applied or attached directly to the disk A, or attached in such a way as to receive motion therefrom, and in these figures the weightsD are attached to levers J, pivoted at one end upon the axis B of the disk, and supported each by a spring, E, so that a jolt, jar, or swaying motion will cause the weights to have an up and-down motion. Each lever in Fig. 3 is provided with a pawl. j, to engage with the teeth of the disk A for revolving the disk. The pawls j j in Fig at are sharp at the point to engage with the smooth edge of the disk A and cause it to revolve. A stop-pawl, It, is employed in Figs. 1, 2, 3, and i to prevent the disk A from turning backward.

In Fig. 5 the weighted levers are provided with cams a for turningthe disk, and said cams are attached to the weights by light springs Z, and the disk is prevented from backward movement by a similar cam or wedge at the top acting between the periphery of the disk and the adjacent end of the projection or arm at, the said cam or wedge being held by the spring at.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

.l. The main casing or support C pivoted or movable disk A, and springs E, attached to the casing or support 0, in combination with the weights D, attached to the springs, and connections acting between the weights and disk for communicating the motion of the springs to the disk A, as and for the purposes set forth.

2. The disk A, mounted upon an axis, the springs E, attached to a support, and the weights D, attached to the levers supported by the springs and the pivot B, in combination with the cams a, attached to springs Z, said springs being attached to the weights D in position to hold the said cams against the periphery of the disk, substantially as described.
